چکیده
In this paper, an offline evaluation method for the cooling capability of three-phase insulated-gate bipolar transistor (IGBT) inverters is presented, which can better emulate real working conditions. With a properly designed sudden-stop control sequence, conventional junction temperature monitoring at low current used to calculate before sudden stop inverter. This solve challenging switching loss calculation issue in methods. Finally, feasibility, and electrical behaviors proposed are validated through experimental tests.

In this paper a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. . The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. The fundamental component of the three-phase line-to-line voltage is increased by about 15 percent above than that of the conventional sine-wave inverter. The sinusoidal PWM switching scheme allo...
متن کاملNew Coupled-Inductor Based Multilevel Inverter with Extension Capability
Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
